Long-term micrometeorological measurements
(1998-2004) show high interannual variability in the atmosphere-ecosystem
exchange of carbon for a Pacific Northwest
coniferous old-growth forest. Earlier
work [Wharton et al. 2004] has shown that net ecosystem exchange of carbon (NEE)
in this forest is highly sensitive to any perturbations in climate, and in
particular, in precipitation and temperature anomalies. Here we present results
from the ACASA (Advanced Canopy Atmosphere-Soil Algorithm) model to investigate
NEE as it relates to various climate forcings, including a shift in precipitation
pattern and increase in air temperature.
